Clang is inserting an llvm.memcpy function call into my program where it does not exist (the code never calls memcpy), is there a particular reason for this? It also looks like it's inserting two other artificial function calls, something to do with llvm.lifetime.start and llvm.lifetime.end, what are these functions and why are they being inserted artificially? Thanks. -------------- next
